This'invcntion relates to lighting devices of the class used forlighting gas burners and for similar purposes, and the object of theinvention is to provide an improved device of this class which is simplein construction and operation, and winch may be convenientlymanipulated, and with thisv and other objects in view the inventionconsists in a device of the class specified,.

constructed as hereinafter described and claimed.

, The invention is fully disclosed in the, following specification, ofwhich the itCCOIlI- panying drawin forms apart, in which the separateparts 0 my improvement are designated by suitable reference charactersin each of the views, and in which;

Figure 1 is a side view rof my improved lightmg device and showingth'eparts thereof in position for use -Fig.,2 view' similar to Fig. 1, butshowing the parts in a ditl'erent position ;F;ig. 3a view-looking in thedirection of arrow 3 of :Fig. 2;-Fig.';4 a view similar .to Figs. 1andQ, but showing only a part of the device, and showing the partsthereof in a different position,;-Fig.

' Fig. 7 a View similar to Fig. 4:, but showing only one part of thedevice and showing one step in the formation thereof, and ;-Fig. 8 aview of that part of the device shown in Fig. 7 and showing another stepinthc formation thereof.

In the practice of my invention I provide a lighting device of the classspecified, the general form of which is old and well known and whichcomprises a main spring arm a and a supplementalsp. ing arm I) connectedatone end by an open sprlng ring a formed integrally therewith and theend of the arm tr is provided with a semicircular head a having acrossbar d, one side of which is provided with a file or roughened ignitingsurface as shown at (2 and all the parts a, b,

0 undo are preferably composed of a strip of flat spring metal.

The end a of the semicircular head a or of the bow which forms saidhead, is beveled at one or botlr edges thereof as shown at a and theobject of this construction will be hereinafter described.

The free end portion I) of the supplemental spring arm Z) is bent orturned at right angles to the main part thereof and is bent on thetransverse line 71 shown in Fig.

7 to form a head piece I) of double thicknoss, but before bending saidpart b at I), the extreme end portion 1) is tapped to form an aperture band after the bending of the end portion I) to form the double head I)",the

said head isslotted longitudinally as shown at U to form two spring jawsb as clearly shown in Figs. 1, 2, 4and 8.

I also provide a scratch or igniting plug 0 which, in the operation ofthe device, bears -on the roughened surface d of the bar (Z and whichproduces sparks by which the gas is ignited.

The Plug e is of well known material and similar to other devices of itsclass now in use and said plug is provided with a neck portion e whichfits in the aperture I) and said neck portion bears on the upper side Z1of the head L, while the head of said plug bears on the inner side 31 ofsaid head, as clearly shown, and the action of the spring jaws b of saidhead securely hold said plug in position.

In order to remove the plug 6- or substitute a new one, the device islaid on a table or other support and the spring arm I) is swung into theposition shown in Fig. 1 and pressed downwardly so that one of thebeveled edges at a? of the semicircular head a will enter the slot 1) inthe head I) and force the jaws 'removed as will be readily understood.

My invention relates particularly to the formation of the head I) andthe slotting thereof together with the diminution of at least one edgeof the end portion a of the semicircular head a of the arm a so as tofacilitate the attachment and detachment of the plug 6.

The operation of this device will be exactly the same as others of itsclass now in use.

In order to ignite a gas jet, the arm 6 is swung into the position shownin Figs. 1

and 6, in which position the scratch orignitmg plug 6 bears on the bar(Z which forms the other scratch or igniting member as v shown in Fig.6, and the arms a and Z) being one end, one ofsaid arms being providedat its free end with atransverse bar and the other with a head adapted.to bear thereon, said head being provided with a longitudinal slotforming" two spring jaws, and a scratch or igniting plugdetachablymounted between said jaws.

2. A lighting device of the class described comprising two spring armsconnected at one end, one of said arms being provided at 'its free end,with a transverse bar and the other with a headadapted to bear thereon,sald head being provided with a longitudinal slot forming two springjaws, and a scratch or igniting plug detachably -mounted between saidjaws, and said device being also provided at one end of said transversebar with a reduced edge adapted to enter the slot in said head.

3. A device of the class described provided with a spring arm having alongitudinally slotted head. composed of two parts folded I one upon theother, one of said parts being provided in the plane of the slot with anaperture, and a scratch plug having a neck adapted to enter saidaperture.

i 4-. A device of the class described comprising two spring arms one ofwhich is bent at one end to form a semicircular head in which 'ismounted a transverse bar, the end of the bend which forms saidsemicircular head being provided with a beveled edge, the

other spring arm being provided with a -slotted head forming spring jawsbetween which is1 detachably mounted an igniting scratch Iiitestimonythat I claim the foregoing as my invention I have signed myname in presence of the subscribing witnesses this 6th day of February1911.
